中水回用工业废水处理能耗计算与表达方法

[中文适用范围]： 本文件列出了废水和污泥处理中能量回收的定量表征以及如何在总能耗计算中对此进行核算的一般原则和指导。本文件的范围包括： — 适用于工业废水处理和污泥处理再利用的主要能量回收过程的定义，例如产生沼气的厌氧消化； — 介绍能量回收过程和系统产生的能量的可能形式，例如电、蒸汽或热能，以及如何核算沼气的故意浪费或商业利用； — 关于量化所产生能量时应考虑的值的指导，包括平均实际产生的功率； — 在任何使用之前允许的沼气中受污染成分的限量； — 按照以下原则将能量回收结果与能耗相结合：未从废水或污泥处理过程中回收的能源生产不属于本文件的范围，也不包括在本文件的计算和结果中。 [外文原描述]： This document sets out the general principles for, and provides guidance on, the quantitative characterization of energy recovery from wastewater and sludge treatment, and how to account for this in the total energy consumption calculation. The scope of this document includes: — a definition of the main energy recovery processes applicable to industrial wastewater treatment and sludge treatment for reuse, such as anaerobic digestion yielding biogas; — an introduction to the possible forms of energy generated by energy recovery processes and systems, such as electricity, steam or heat, and how to account for intentional wasting or commercial utilization of biogas; — guidance on the value to be taken into account as quantification of the energy generated, including the power actually generated on average; — a limit level for contaminated components in biogas allowed before any utilization; — principles to integrate the energy recovery results with the energy consumption in accordance with ISO 21939-1. Energy production which is not recovered from wastewater or sludge treatment processes is not within the scope of this document and is not included in the calculations and results expressed in it.
